GAS SENSOR AND CORRESPONDING PRODUCTION METHOD

摘要

A gas sensor and a method for its manufacture are described. The gas sensor has a solid electrolyte (11) having at least one measuring electrode (15) and one porous protective coating (16). The measuring electrode (15) has an electrically conductive base layer (25) and a further layer (27), the further layer (27) being deposited in the pores of the porous protective coating (16) adjacent to the base layer (25) via galvanic deposition. In order to deposit the further layer (27) via galvanic deposition, the basic body (10), which has been fused with the base layer (25) and the protective coating (16) via vitrification, is immersed in a galvanizing bath, the base layer (25) being connected as the cathode.
